It provides an 8-bit MCU and a 8 channel wavetable synthesizer. The program ROM is composed of both program control codes and wavetable voice codes, and can be easily programmed. The HT36A4 has a built-in 8-bit microprocessor which programs the synthesizer to generate the melody by setting the special register from 20H~2AH. A HALT feature is provided to reduce power consumption.

In the case of RC operation, OSC2 is the output terminal for 1/4 system clock (fOSC2=fOSC/8). The system clock may come from the crystal, the two pins cannot be floating. ¾ Absolute Maximum Ratings Supply Voltage .........................
